If the speaker panel needs to be removed, a mir-
ror programming port connector is provided on
both backplanes.

both backplanes.
Programming for Series I 800 MHz units is done
via EPROM and is detailed in section 6.1. The
RJ11 front port is covered (not used).

Dual Power Supply module
The Dual Power Supply module is made up of
two separate power supply units coupled in a
single chassis.

Refer to Table 1 on page 7 for tabular listing of
power supply LEDs indicators.
Refer to Figure 1 for the front panel LED layout.
This module has:
power supply LEDs indicators.
Refer to Figure 1 for the front panel LED layout.
This module has:
•
Two “Power” red-colored pushbutton
switches - Push in for ON and release out
for OFF. Control complete power distribu-
tion to the Radio assembly
for OFF. Control complete power distribu-
tion to the Radio assembly
•
Two “ON” LEDs - light green when push
button is ON; DC power is distributed to ra-
dio modules. Flash green in conjunction with
the “OL” LED when an over voltage condi-
tion is present.
dio modules. Flash green in conjunction with
the “OL” LED when an over voltage condi-
tion is present.
•
Two “Stby”- Standby voltage LED, lights
red when push button is off; AC power is
applied but DC is not distributed to radio
modules. To remove presence of voltage,
disconnect both power cords.
